Ed Barnes gave his last expert pre-session talk for 2017 on 28 November. It was an intermediate/advanced level talk delivered in Ed's brilliant style taking us on a journey and introducing us to some advanced signalling techniques in the context of when they are critically useful.
If you missed out on the talk or want to revisit it at your leisure, have a look at Ed's notes on Missing Signals.
We hope to see more of Ed in 2018. Keep your eyes and ears open.
